 It is known that initial data for interpretation of results of research of structure of a seabottom by means of an acoustic profile recorder is profile chart – a dependence of capacity of reflected signal on a delay (depth) along a line of measurements. Using in profile recorders coherent broadband signals, digital registration of a full signal opens use possibility, in addition to capacity (amplitude) of received signal, also spectral characteristics of the reflected signals for research of structure of a sea ground.
